AK4671 supports analog mixing function from each line input to each line output
When the analog mixing is used, A/D converter is also available if PMADL or PMADR bit is “1”. When
PMAINL1=PMAINR1=PMAINL2=PMAINR2=PMAINL3=PMAINR3=PMAINL4=PMAINR4=PMMICL=PMMICR
bits = “1”, the input resistance of LIN1/RIN1/LIN2/RIN2/LIN3/RIN3/LIN4/RIN4 pins becomes 25k Ω (typ) at
MGNL/R0 bits = “0” and 20k Ω (typ) at MGNL/R0 bits = “1”, respectively.
L1G1-0, L2G1-0, L3G1-0, L4G1-0 and LPG1-0 bits adjust the gain for each path
